python selenium 爬取百度翻译单词音标

python selenium 小爬虫

主要流程 读取excel文件中的单词——利用selenium 去百度翻译中获取单词对应的音标——写入cvs文件

selenium 安装 环境配置略过

谷歌浏览器打开百度翻译并等待baidu_translate_input加载完成
browser = webdriver.Chrome()
url = “https://fanyi.baidu.com/?aldtype=85#en/zh/”

browser.get(url)
WebDriverWait(browser, 1000).until(EC.presence_of_all_elements_located((By.ID, ‘baidu_translate_input’)))

打开excel文件，并获取单词sheet的 行数
excelfile = xlrd.open_workbook(r’F:\studytest\word.xlsx’)
sheet = excelfile.sheet_by_name(“单词”)
cnt = sheet.nrows

csv文件写入标题
with open(r’F:\studytest\result.csv’, ‘a’, encoding=‘utf-8’,newline=’’) as csvfile:
writer = csv.writer(csvfile)
writer.writerow((“单词”, “音标”))

定位baidu_translate_input并输入单词
browser.find_element_by_id(‘baidu_translate_input’).send_keys(mystr)

点击翻译
browser.find_element_by_id(‘translate-button’).click()

获取音标
phonetic = browser.find_element_by_class_name(‘dictionary-spell’).text # 音标
